Embodiment Construction

[0043] Referring to Fig. 2, the present invention mainly consists of three logical entities: an access requester AR, an access controller AC and a policy manager PM, which can be distributed anywhere in the network. Access requester AR is also called requester, user station, etc.; access controller AC is also called authentication access controller, base station, access service unit, etc.; policy manager PM is also called authentication server, trusted server, background server Wait. The access requester AR communicates with the access controller AC through the protocol interface network, the access controller AC communicates with the policy manager PM through the protocol interface network, and the policy manager PM communicates with the access requester AR through the access controller AC.

[0044] The access requester AR is mainly composed of the network access requester NAR, the TNC client TNCC and the access requester’s integrity collector IMC 1 constitute. The network ...

Abstract

The invention provides a trusted network connection system based on ternary equal authentication, wherein a network access requester is connected with a TNC client-side by a data carrying manner, and a TNC client-side is connected with an integrality collector by an integrality measurement collecting interface. A network access controller of an access controller is connected with a TNC service side by the data carrying manner, the TNC service side is connected with an integrality collector by the integrality measurement collecting interface. A user authentication service unit of a policy manager is connected with a platform evaluate service unit by the data carrying manner, and the platform evaluate service unit is connected with an integrality verifier by an integrality measurement verify interface. The invention solves the technical problems in background technology that expandability is poor, the key arrangement process is complex, and the security is low. The network access layer and integrality evaluate layer of the invention use ternary equal authentication to realize a two-way user authentication and a platform integrality evaluate, so, the invention can improve the security of the whole trusted network connecting construction.

Description

technical field [0001] The invention belongs to the technical field of network security, and in particular relates to a trusted network connection system based on ternary peer-to-peer authentication. Background technique [0002] With the development of informatization, the problems of malicious software such as viruses and worms are extremely prominent. There have been more than 35,000 kinds of malicious software, and more than 40 million computers are infected every year. To contain such attacks, it is necessary not only to solve the problem of secure transmission and data input checks, but also to start defense from the source, that is, from every terminal connected to the network. However, traditional security defense technologies have been unable to defend against a wide variety of malicious attacks. [0003] In response to this problem, the International Trusted Computing Group TCG has specially formulated a network connection specification based on trusted computing...
